The RT6273A/B is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 17V. The device possesses an accurate reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency.
The RT6273A/B adopts Advanced Constant On-Time (ACOT®) control architecture to provide an ultrafast transient response with few external components and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RT6273A operates in automatic PSM that maintains high efficiency during light load operation. The RT6273B operates in Forced PWM that helps meet tight voltage regulation accuracy requirements.RT6273AHGJ6F
